Ruby 2.4.0

[voxxit]

Ruby 2.4.0 (patchlevel 0) was released on 2016-12-25. Just curious when we can expect to see it added to Chef 11?

Something tells me this should be automated, at least as a beta/opt-in feature... :-)

+1 Sure. Why not. (Despite all appearances that AWS has abandoned support for OpsWorks improvements on the old stack.)

Hi, I would like to know if it is possible to have apps that use different Ruby versions in the same stack.

I would like to deploy two apps. One uses Ruby 2.1.8 and the other one Ruby 2.4.0

Thanks.

@interpegasus I don't see a clean way to pull that off. The Ruby version is a setting on a layer, and there's no way to override that per app. To be honest, I don't even see a dirty way to pull that off.

@githuesch Thanks for the fast reply.
I will switch the apps and layer, to the latest supported ruby version 2.3. While 2.4 support is implemented.

@githuesch Any word on this? How can the community help out with this going forward to ensure we're not lagging behind :)

@voxxit The only thing the community can really do is to express the need for Ruby 2.4 with +1's in this thread. This helps us prioritize this task against others.

Well, this is a +1 with a bump.

[inopinatus]

+1 it is then.

+1, just updated my app to run on 2.4.1, but just realized i can't run it on my opsworks setup.

(Note: This is only for Ubuntu 14.04. Other OSes are on your own...)

I was able to get this to work on my own. I had to do a few things.

First, you need a .deb for Ruby 2.4.1. In order to figure this out, I downloaded the Ruby 2.3.4 .deb, extracted it (.debs are .ar files with a control.tar.gz and data.tar.gz inside), and opened up the usr/local/lib/ruby/2.3.0/x86_64-linux/rbconfig.rb file. That contains the exact configure args (CONFIG["configure_args"]) that were used to build Ruby. I used that to build my own copy of 2.4.1 on a x86_64 Ubuntu 14.04 box:

apt-get install gcc autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm3 libgdbm-dev
wget https://cache.ruby-lang.org/pub/ruby/2.4/ruby-2.4.1.tar.gz
tar zxfv ruby-2.4.1.tar.gz
cd ruby-2.4.1/
./configure --prefix=/usr/local --enable-shared --disable-rpath --disable-install-doc
make

I noticed the deb was built with fpm, so I installed that to do my eventual packaging:

apt-get install ruby ruby-dev
gem install --no-ri --no-rdoc fpm

One last thing I needed to duplicate the build was to get the right post-install script. I created a postinstall file with these contents:

#! /usr/bin/env sh
/sbin/ldconfig

OK, so now we're ready to package things up.

make install DESTDIR=/tmp/installdir/
fpm -s dir -t deb -n opsworks-ruby2.4 -v 2.4.1-1 -C /tmp/installdir --after-install=./postinstall

Out pops a opsworks-ruby2.4_2.4.1-1_amd64.deb file for you to use. You can use dpkg -c opsworks-ruby2.4_2.4.1-1_amd64.deb to make sure it's got the right stuff in it. Here's a copy of my build that we're using in production. Use this at your own risk, as I may have messed something up!

https://www.dropbox.com/s/1hjlnj6x0lco0d6/opsworks-ruby2.4_2.4.1-1_amd64.deb?dl=0

To actually use this, you need to get OpsWorks to download from a URL you control. The default URL can be overridden via stack JSON. So, create an S3 bucket and upload the .deb under a packages/ubuntu/14.04/ folder. (Don't forget to make the bucket/files public!) Then add this to your stack JSON:

  "opsworks_commons": {
    "assets_url": "https://my-opsworks-bucket-o-stuff.s3.amazonaws.com"
  },

To ensure you don't break things if you don't update the ruby version right away, you can also place the other .debs that OpsWorks pre-built into that bucket at that path. They're available at https://opsworks-instance-assets.s3.amazonaws.com/packages/ubuntu/14.04/opsworks-ruby2.3_2.3.4-1_amd64.deb and you can adjust the URL to grab ones for other versions of Ruby that you have in use currently.

OK, last part is to get OpsWorks to use this version of Ruby. While they don't have a preset for 2.4, you can configure it yourself. So, add this to your stack JSON:

  "ruby" : {
    "major_version": "2",
    "minor_version": "4",
    "patch_version": "1",
    "pkgrelease": "1",
    "full_version": "2.4",
    "version": "2.4.1"
  },

That will override whatever version you have set for your layer. You should be able to deploy and be on 2.4!

It worked for me, but obviously I can't guarantee success for others. Also, if you have other layer types that depend on other binaries (Node, PHP, etc, and probably MySQL/Memcached too), you'll need to upload those .debs to your bucket as well (since you're overriding the assets_url for the whole stack).

TL;DR I built a custom binary .deb for Ruby 2.4.1, hosted that on an S3 bucket, and configured my stack JSON to use that binary and ruby version.
